Pré-publication, Document de travail: This paper revisits two classical problems in the theory of voting-viz. the divided majority problem and the strategic revelation of information by majority vote-in the light of evolutionarily founded partial Kantian morality. It is shown that, compared to electorates consisting of purely self-interested voters, such Kantian morality helps voters solve coordination problems and improves the information aggregation properties of equilibria, even for modest levels of morality.
